%description
Builds semantic topic models from 'Sentence-BERT' embeddings (Reimers and
Gurevych, 2019) <doi:10.18653/v1/D19-1410>. Sentence embeddings are
computed in several modes with models run on the Open Neural Network
Exchange ('ONNX') Runtime, including multilingual and long-context
encoders and a fast static model. Topics are labeled with class-based term
weighting that can be retuned without refitting. Candidate topic counts
and document granularities (whole documents, sentences, clauses, or
phrases) can be compared side by side, and fitted models assign topics to
new documents, give soft memberships and per-document topic mixtures. The
package offers coherence and diversity metrics and visualizations.
